I’ve been there many times. Once I was on a conference call with John Walton when one of my kids came into the home office to announce loudly that he had to poop faster than I could hit the mute button. And I’ve had several radio interviews with screaming kids barging in. But now they are all grown and I miss them barging in. And the truth is no one really minds having kids interrupt discussions about education. And if they do, forget them.
